Crop simulation models are valuable tools for quantifying crop yield response to water, and for devising strategies to improve agricultural water management. However, applicability of the majority of crop models is limited greatly by a failure to provide open-access to model source code. In this study, we present an open-source version of the FAO AquaCrop model, which simulates efficiently water-limited crop production across diverse environmental and agronomic conditions. Our model, called AquaCrop-OpenSource (AquaCrop-OS), can be run in multiple programming languages and operating systems. Support for parallel execution reduces significantly simulation times when applying the model in large geospatial frameworks, for …

Daugherty Water for Food Global Institute: Faculty Publications
In 1965’s United States v. Shurbet case, an irrigator from Texas asserted his claim for a depletion tax deduction for groundwater pumped from the High Plains Aquifer. He argued that the unique conditions of the southern High Plains region - a plateau where the shallow aquifer is recharged only through precipitation at a slow rate - meant the groundwater resource would be depleted in time. The state argued that groundwater was not fundamentally an exhaustible natural deposit, but the Supreme Court concluded the tax deduction was appropriate given the “peculiar” conditions in the area. It was stated the decision was …

Without a transformative leap forward in the use of irrigation, Africa will continue falling short in the struggle to feed its growing population, improve its people’s nutrition, grow its economies, adapt to the impacts of climate change, and eliminate poverty. While Africans must lead this transformation for it to be successful, the international community can help African countries substantially increase the use of more productive and sustainable water management practices and unlock the potential of farmer-led irrigated agriculture. Achieving highly productive irrigated agricultural systems in Africa requires an enabling environment that facilitates the full engagement of farmers, public and private …

Malta : Natural Freshwater Resources, Lisamarie Pereira
Global Public Health
The aim of this paper is to discuss Malta’s struggle with limited natural freshwater resources. Malta currently uses aquifers to obtain natural freshwater. For over a decade, aquifers have been under pressure from over-abstraction. Due to this issue, Malta has not been able to obtain enough natural freshwater for agriculture and basic living. The biggest risk due to over-abstraction is retrieving a smaller volume of freshwater. In Malta’s attempted interventions, the biggest issue is the Maltese government’s misconceptions. The Maltese government believes the country has unlimited natural freshwater resources. Due to this misconception, nothing is being done to actively fix …

Burundi : Water Scarcity, Isabel Salas
Global Public Health
Burundi is located near the African great lakes region of East Africa. This country is one of the poorest and hungriest countries throughout the world because of this they are facing multiple problems with communicable disease. These families are seeing a reduction in the amount of water available to them and based on this they are receiving water from external sources such as wells and lakes. Most of the water throughout Burundi is contaminated with Phytoplankton which increase cholera outbreaks in this area. It has also been shown that uranium impacts the water throughout the wells and lakes. Both of …

Chad : Hepatitis E, Hanna Pegarsch
Global Public Health
Contaminated drinking water in Chad is the main source for a Hepatitis E outbreak, leading Chad citizens to develop severe illness including jaundice, liver-failure, miscarriage, and death. There are 0.4 physicians for every 10,000 people living in Chad needing healthcare. Of the citizens in Chad, only 42% have access to uncontaminated drinking water. With such a long incubation period for Hepatitis E, the citizens don’t know they are spreading the illness to the rest of their community. Even with the symptoms, the citizens don’t have the access or the capacity for treatment, making Hepatitis E an epidemic in Chad.

Smoothing-Based Compressed State Kalman Filter For Joint State-Parameter Estimation: Applications In Reservoir Characterization And Co2 Storage Monitoring, Y. J. Li, Amalia Kokkinaki, E F. Darve, P K. Kitanidis
Environmental Science
The operation of most engineered hydrogeological systems relies on simulating physical processes using numerical models with uncertain parameters and initial conditions. Predictions by such uncertain models can be greatly improved by Kalman-filter techniques that sequentially assimilate monitoring data. Each assimilation constitutes a nonlinear optimization, which is solved by linearizing an objective function about the model prediction and applying a linear correction to this prediction. However, if model parameters and initial conditions are uncertain, the optimization problem becomes strongly nonlinear and a linear correction may yield unphysical results. In this paper, we investigate the utility of one-step ahead smoothing, a variant …

Why Do Different Drought Indices Show Distinct Future Drought Risk Outcomes In The U.S. Great Plains?, Song Feng, Miroslav Trnka, Michael Hayes, Yongjun Zheng
National Drought Mitigation Center: Faculty Publications
Vigorous discussions and disagreements about the future changes in drought intensity in the U.S. Great Plains have been taking place recently within the literature. These discussions have involved widely varying estimates based on drought indices and model-based projections of the future. To investigate and understand the causes for such a disparity between these previous estimates, the authors analyzed the soil moisture at the near-surface soil layer and the entire soil column, as well as the Palmer drought severity index, the Palmer Z index, and the standardized precipitation and evaporation index using the output from the Community Climate System Model, version …

National Drought Mitigation Center: Faculty Publications
Improved understanding of the water balance in the Blue Nile is of critical importance because of increasingly frequent hydroclimatic extremes under a changing climate. The intercomparison and evaluation of multiple land surface models (LSMs) associated with different meteorological forcing and precipitation datasets can offer a moderate range of water budget variable estimates. In this context, two LSMs, Noah version 3.3 (Noah3.3) and Catchment LSM version Fortuna 2.5 (CLSMF2.5) coupled with the Hydrological Modeling and Analysis Platform (HyMAP) river routing scheme are used to produce hydrological estimates over the region. The two LSMs were forced with different combinations of two reanalysis-based …

The objective of this study was to develop information mining methodology for drought modeling and predictions using historical records of climate, satellite, environmental, and oceanic data. The classification and regression tree (CART) approach was used for extracting drought episodes at different time-lag prediction intervals. Using the CART approach, a number of successful model trees were constructed, which can easily be interpreted and used by decision makers in their drought management decisions. The regression rules produced by CART were found to have correlation coefficients from 0.71–0.95 in rules-alone modeling. The accuracies of the models were found to be higher in the …

National Drought Mitigation Center: Faculty Publications
Ensuring global food and water security requires a detailed understanding of how coupled socio-environmental systems respond to drought. Using the Platte River Watershed in Nebraska (USA) as an exemplar mixed urban-agricultural watershed, we quantify biophysical response to drought in urban (Lincoln NE) and agricultural systems alongside a qualitative analysis of governance response and adaptive capacity of both sectors. Synthesis of results highlights parallels and discontinuities between urban and agricultural preparations for and response to drought. Whereas drought prompted an increase in well installations and expansion of water-intensive crops, e.g., corn, in the agricultural sector, outdoor water use restrictions rapidly curtailed …
